 RooAddModel is an efficient implementation of a sum of PDFs of the form

\[ c_1 \cdot \mathrm{PDF}_1 + c_2 \cdot \mathrm{PDF}_2 + ... + c_n \cdot \mathrm{PDF}_n \]


\[ c_1 \cdot \mathrm{PDF}_1 + c_2 \cdot \mathrm{PDF}_2 + ... + \left( 1-\sum_{i=1}^{n-1} c_i \right) \cdot \mathrm{PDF}_n \]

The first form is for extended likelihood fits, where the expected number of events is \( \sum_i c_i \). More...
